Which DDR3 4gb RAM?

Hey, I'm wanting to buy some DDR3 1600mhz RAM for my i5 750 build. I have picked out two choices of RAM from Ebuyer which are either 1.5v or 1.65v (scan and overclockers currently are lacking in their DDR3 sections) and I really need some advice on which would be best suited for my build.

Other information:
My motherboard is a MSI GD65.
I will be overclocking.
I have 64bit Windows 7.

G.skill Ripjaws hands down dude!
look at the RAM timmings on both products, the G.skill kicks the Kingston's ass all over the place in terms of timmings (in case you don't know - the lower the timmings are, the better preformance would be, anything lower then 8-8-8-24 is great and the G.skill offers 7-8-7-24 wich is greaaat!)

forget the extra vlotages its so much better then the Kingston you won't belive the preformance on it compared to the kingston.
